325i Convertible Top Replacement ..... Help

I am told that there was a video that was sent out by BMW to dealers when the e30 Cabriolet was released. The video covers everything from operation to replacing and adjusting the top and frame, adjusting the windows, and body changes. Does anyone out ther have one they would be willing to sell, rent, copy or share - I am about to install a top on my '87 325i and I underrstand this tape is a big help....
Thanks,
Irish
